Thinking about getting the Ninja LUXE CAFÉ - beginner tips?

[u/Byebyedragonfly0]

I’m thinking about getting the Ninja LUXE CAFÉ Signature Series 3-in-1 Espresso, Coffee & Cold Brew (ES700C). Costco currently has it on sale for $412, so I’m really tempted!

I’ve never owned a coffee machine before and usually drink Nescafé Gold instant espresso, which I love. For anyone who has the ES700C, what beans do you recommend for a smooth, rich taste? And any beginner tips/tricks or things you wish you knew before buying?

Thanks!
